CLOSURE FOR RECEPTACLES.

Application filed May 2, 1913. Serial No. 765,163.

Specification of Letters Patent.

Patented Apr. 21, 1914..

To all who, it may concern lie it known that I, FRIEDRICH \VAIKE, subjectof William II, Emperor of Germany, residing at Akron, in the county of Summit and State of Ohio, have invented new and l the axis of the receptacle and communicatuseful Improvements in Closures for Receptacles, of which the following is a specification.

'lnis invention relates to improved closure devices for receptacles such as milk bottles and the object thereof is to provide a closure device for such a. receptacle which will effectually and temporarily seal the open mouth of the receptacle and leave no place for lodgment of dirt or other foreign substances to thereby render the receptacle as nearly sanitary as possible.

The invention contemplates providing a closure device for receptacles of such construction that the upper open end of the receptacle may be thoroughly washed or cleaned previous to the removal of the closure member without the cleansing fluid entering the receptacle.

With the foregoing and other objects in view, the invention consists in the novel constr lotion, combination and arrangement o if parts constituting the invention to be hereinttfter specifically described and illus- .tztated in the accompanying drawings which form 2 part hereof wherein is shown the preferred embodiment of the invention, but it is to h understood that changes, variations and n difications can be resorted to which come vit-hin the scope of the claim hereunto appended.

Tn tl e drawings in which similar reference nunier ls indicate like parts in the different [figure 1, is a vertical, central, secview of the upper open end of a receptac e c uigbodying this invention and approxin'iatcljf on line X of Fig. 2; and, Fig. l, is a plan lvi'ew of the receptacle such as is shown in section in Fig. 1. 1

Referring tti the. drawings in detail, 1 denotes a receptacle usually provided at its mouth with an gannular laterally-extending bead 2 such as is now in common use on receptacles for delivering milk. In the upper face of the mouth portion of the bottle is an annular groove or channel 3 preferably provided with concentric sides. The inner portion 4 of the mouth of the bottle may be slightly rounded if desired and the upwardly-extending portion 7 forms.an antional nu'lar wall with its upper edge preferably in the same horizontal plane as the upper face of the bead 2. Extending from the channei 3 are one or more grooves or channels 8 preferably arranged radially with respect to ing with the bottom of the channel to provide drains or discharge openings for a purpose to be later described.

H The closure device which I preferably employ consists of a disk 9 of suitable material, preferably card board, provided with a downwardly-turned marginal flange 10. the inner diameter of which is approxi mately the same as the inner diameter of the channel 3 or the outer diameter of the wall 7. The relative proportions of the marginal flange 10 and the inner wall of the channel 3 are such that when the closure device is positioned as shown in the drawings the inner face of the marginal flange 10 will snugly engage the outer face of the wall 7 and form therewith a substantially fluidtight joint. \Vhen it, is desired to remove theclosure device it is lifted from place by means usually employed for removing this type of closure device, and the contents of the receptacle may then be poured out without the contents of the receptacle coming in contact with any dirt-catching portion of the receptacle.

It will be obvious that in view of the fact that the closure device completely covers and forms a snug joint with the wall 7 no extraneous matter can find lodgment thereunder and if it is desired to more thoroughly cleanse the receptacle before opening, water may be poured on top of the receptacle which flows into the'channel 3 and thence drains outwardly through the channels 8 after which the closure device may be displaced and the contents removed.

This device also affords means whereby a receptacle may be sealed and a piece of melting ice may be placed on top of the receptacle for cooling the contents, the water from the melting ice flowing into the channel 3 and thence draining outwardly through the discharge openings 8 without coming into contact with the contents of the receptacle.

From this it' will be obvious that the device aflords a perfectly sanitary closure device for receptacles adapted to contain substances: which might be injured by contact with foreign substances.

I claim;

A milk bottle provided in theopen end thereof with an annular channel and further provided in said open end with a plurality 6 of lateral channels leading outwardly from the annular channel to the periphery of the bottle neck and constituting drain outlets, the bases of said drain outlets sloping downwardly' and outwardly, and -a cap having a Y 10 marginal depending flange of less depth than the channel and frictionally engaging the inner wall of the channel, there being a space between the outer Wall of the channel and said flange, for the purpose described.

In testimony whereof I have hereunto set 15 my hand in presence oftwo subscribing witnesses. I

FRIEDRICH VVAIKE.
